.mrrusnn Application filed July 24, 1922, Serial No. 577,214.

To all whom it may concern.

Be it known that I, ERNEST a citizen of the United States, residing in Pelham .Manor, county of Westchester, State of New York, have invented certain new and useful Improvements in Diffusers, of which the following is a specification.

My invention relates to diffusers for use in connection w1th devices for the combustion of fuel in which the air is restricted to a circulating or whirling motion, and has for its object the production of a baffle plate which will prevent air from passing in a straight line, but will permit the air to pass which has either rightor left hand whirling motion.

A further object is to provide a deflecting plate simple in construction that will'withstand intense heat without melting.

The foregoing and other features of my invention will now be described in connection with the accompanying drawings forming a part of the specification, in which I have represented my diffuser embodylng the improvements in the preferred form, after which I shall point out more particularly in the claims those features which I believe to.

be new and of my own invention.

Referring to the accompanying drawings in which similar characters of reference indicate like parts throughout the several views: v

Figure 1 is a plan view of my diffuser.

Figure 2 is. section along the lines w-y, Figure 1.

Figure 3 is an enlarged detail, illustrating a method of connecting the outer-ends of the sectors.

Figures 4 toll are modified details which I have employed.

In the carrying out of my invention I provide substantially a conical plate 1 with the smaller or restricted end 2 provided with a flange 3 which may be providedv with a thread 4 or other means adaptable to secure the diffuser upon the end of a fuel supplying device. The conical portion is divided up into a plurality of sectors 6. Alternate sectors though integral at the restricted end diverge so that they lie in the surfaces of two coaxial cones of different angle at the ver- 'tex. The outer ends of the sectors are joined together by any convenient means shown at 8. It will be readil understood that the angle at the vertex 0 the outer cone may be any angle approaching 180 and even a H. PEABODY,

' plane surface may beused with the other set of sectors lying in the surface of a cone- The peep-hole 9 is provided for observation purposes, and when positioned under the restricted end it permits any surplus oil to drip out by gravity.

'It will be perfectly evident by referring to Figure 1 that air is prevented from passing through the diffuser in a straight line, while should it have a whirling motion imparted to it, the air can pass the diffuser in either right or left hand direction following the path of the whirl without any obstruction.

I am aware'that flaring dampers or conical air deflecting plates have been used before, on the end or proximity of a fuel supplying device,-having vanes set at an angle to the surface of the cone shaped damper for the purpose of imparting a whirling motion but I do not know of a device of the character described that will permit air whirling to the right or left to pass unobstructed in either direction and at the same time prevent air passing through it in a straight line. It will be observed that in my difiuser the sectors lie in the surfaces of two cones and are not inclined to the surfaces of the cones. e

What I claim and desire to secure by Letters Patent of the United States is 1. A. diffuser comprising a frusto-conical member consisting of a plurality of sectors, one series of which lie in the surface of a cone and the other series of which lie in the surface of a coaxial cone of greater angle at the vertex.

2. A diffuser comprising two series of sectors integrally formed. one series of sectors lying in the surface of a cone, and the other series of sectors lying in the surface of a coaxial cone having a different angle at the PATENT arms. p

vertex, and the sectors of one series alter- 4 natin with the sectors of the other series.

3. device as recited in claim 1 with the addition of means for connecting the sectors on their periphery- 4. A device as recited in claim 1 in which the diffuser is provided with a lateral opening near its restricted end.

5. The combination with a burner of a diffuser in the form of a frustum of a cone having a restricted opening at the smaller end through which the burner projects, the frusto-conical member comprising a series of sectors lying in the surface of a cone and a series of sectors lying in the surface of a co-axial cone with a different angle at the vertex, the sectors of the two series alternating.

6. The combination with a burner, of an air deflecting device in the form of a frusturn of a cone having a restricted opening at the small end thereof through which the burner extends, said frnsto-conical member having openings and portions opposite said openings and spaced therefrom in order that the openings may permit direct entry of current having a motion of rotation about the axis of the cone.

8. A diffuser comprising a frusto-conical member consisting of a plurality of sectors, one series lying in the surface of a cone and the other series lying in the surface of a cone having a different vertex angle, and means connecting the sectors at each end, both series of sectors and connecting means being integral.

S). A diffuser comprising a frusto-conical member consisting of a plurality of sectors, one series of which lie in the surface of a cone and the other series of which lie in the surface of a coaxial cone.

In testimony whereof I affix my signature in the presence of two witnesses.
